Application led July 9,

To all whom t may concern:

Be it known that I, Gus'r A. NELSON, a citizen of the United States, residing at Sedro Woolley, in the county of Skagit and State of Washington, have invented new and useful Improvements in Vulcanizers, of which the following is a specification.

This invention relates to a vulcanizer, the general object of the invention being to provide an electrically heated steam vulcanizer for use in small shops, garages and the like and which is so formed that the steam pressure can be quickly raised to a vulcanizing pressure. j Y y Another object of the invention is toprovide means whereby theoperator can apply the pressure to the tube with one hand while i he holds the pressure block or adjusts the tube with the other.

This .invention also consists in certain other features of construction and in the combination and arrangement of the several parts. to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claim.

In describing my invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is a side view of the invention.

Figure 2 is a plan view thereof.

Figure 3 is a longitudinal sectional view.V

Figure 4 is an end' view.-

Figure 5 is a transverse sectional view.

Figure 6 is a plan view showing the heating coils and the insulating means. 'n f In these views 1 indicates the body of the device which is provided with a water chamber 2V and a chamber 3 in which is located the heating coils 4. An inlet pipe 5 is connected with the water chamber and this pipe may be provided with a suitable pressure gage 6. Conductors 7 are connected with the heating coils and with a socket 8 so that the device can be attached to an electric light socket or the like. If desired the pressure gage can be made to shut oif the current when the pressure reaches a certain point, any `Ysuitable means may be provided fon doing this.

gaging a latch part 17 formed on the leven for holding the same in adjusted position. The 'notches are shown at 16 in Figure 4. A slotted tubular member 18 is carried by the lever, the lever passing through the slot therein and a spring 19 is inserted in the tubular member and engages the lever. The

lower end of this tubular member is adapted tol engage a block 2O which is adapted to be placed on that part of the tube whiclil rests upon the topof Vthe device when the tube isbeing vulcanized. Thus the tube is Vheld against the hot u pper surface of the body by means of spring pressure' exerted on the block. This vpressure can be regulated by placing the latch part of the handle in various notches in the upright.

From the above it will be seen that the operator can move the handle or leverwith one hand while he is adjusting the block and tube with the other. The coils being arranged, lasJ shown, right under the water chamber will quickly produce steam when current is turned thereon so that the device can be used in small shops and garages where a vulcanizer cannot be used continuously.. o

It is thought from the foregoing description that the advantages andV novel features of my invention will be readily apparent.

I desire it to be understood that I may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claim.

IlVhat I claim is A vulcanizer of the class described comprising a body having a water chamber inr the upper part thereof, a lower chamber, a heating coil in the lower chamber, a removable bottom plate for the lower chamber, bolts for holding the same in place, the lower ends of the -bolts being extended to form legs and the upper portions of the bolts e slot therein through which the hand lever at one end being extended, it shaft supported passes, a. spring in seid member engaging the by the Xtended portions of these lest menlever` means for introducing Water into the tionedy bolts, ,a hand lever pivvorted. to the chamber and means for connecting the heat- 5 shaft, en upright et the other end of the ing coil with a source oi supply.`

body having notches therein for receiving In testimony whereof I afIiX my signature.

a part ofthe hand lever, a member having GUST A. NELSON.
